medals will be given which graph represents the solution to the given system? y=-2x + 5 and y= 3x - 2
choose the right graph
This is very simple, but I'm on my phone, need paper to do this :/ sry
@tHe_FiZiCx99 YESS I NEED HELPP
I could use a graphing calculator but my browser would crash lol >.> @kelliegirl33 is better at explaining in detail than I am :)
@kelliegirl33 can you help please : (
It is the last one....because when you sub in (-7,19) into both equations, the points satisfy both equations.
thank youuuu i have a few more questions can you help with ?
I can try
which graph represents the solution to the given system? -4x + 2y=-11 and -2x + 2y =-15
-4x + 2y = -11 2y = 4x - 11 y = 2x - 11/2 (the y intercept is -11/2 which equals - 5 1/2 and the slope is 2) -2x + 2y = -15 2y = 2x - 15 y = x - 15/2 (y intercept is -15/2 which equals - 7 1/2 and slope is 1) last graph ( I think)
thank you what about this one how many solutions does the system have ? 2x=-10y+6 and x+5y=3 A.one B.two C.infinitely many D.none
LAST ONE how many solutions does the system of equations have ? y=6x + 2 and 3y-18x = 12 one two infintely many noe
2x = -10y + 6 change to 2x + 10y = 6 which reduces to x + 5y = 3. This is the same as the other equation, therefore there is INFINITE SOLUTIONS ============================================ y = 6x + 2 (sub 6x + 2 in for y in the other equation) 3y - 18x = 12 3(6x + 2) - 18x = 12 18x + 6 - 18x = 12 18x - 18x = 12 - 6 0 = -6 (incorrect) This one has NO SOLUTIONS
OMGGGGGG THANK YOU SO MUCH FOR YOUR HELPPPP !!!! i really appreciate it so much
no problem...glad to help :)
